Problems solved by technology

The friction damper used in the structure is too large and requires a large working space. The friction material is made of a single copper-steel metal material, which makes it difficult to control the change of the friction coefficient, and it is fastened by multiple bolts. Disadvantages such as difficulty in controlling frictional preload

Abstract

The invention discloses a semi-rigid node friction energy dissipation device which comprises a wood column and a wood beam connected with the wood column through a mortise and tenon node. A friction energy dissipation device body is connected between the wood column and the wood beam which are at the mortise and tenon node; the friction energy dissipation device body is connected to the wood column and the wood beam through a beam-end connecting piece and a column-end connecting piece correspondingly; the friction energy dissipation device body comprises a beam-end connecting rod connected to the beam-end connecting piece and a plurality of column-end connecting rods connected to the column-end connecting piece; the multiple column-end connecting rods are connected with the beam-end connecting rod through middle connecting pieces provided with friction sheets in the middles; the friction energy dissipation device body provides stiffness before beam-column nodes conduct displacement and provides frictional energy dissipation after the beam-column nodes conduct displacement. The semi-rigid node friction energy dissipation device relieves the limitation of a friction energy dissipation device in the aspect of friction force control and has the advantages of being high in durability, flexible in use and easy to mount.

Description

technical field [0001] The invention relates to a semi-rigid beam-column joint friction energy-dissipating device with adjustable friction force, which belongs to the field of construction, reinforcement and repair of ancient wooden structures and modern wooden structures and steel structures. Suitable for buildings and structures using semi-rigid joints and hinged points. Background technique [0002] my country's ancient architectural structures have a long history. From ancient palace buildings, temples and halls to residential buildings, a large number of ancient architectural wooden structures are used; at the same time, they are widely distributed, almost all over the country. Many wooden structures have a history of hundreds or even thousands of years. , is an important part of Chinese civilization and contains rich historical and cultural connotations. There are many ancient buildings in our country that have gone through hundreds or even thousands of years. Due to t...
